This little windmill is very sturdy and well built in noncorrosive materials. Just for the first test I put it on a 3m ø50mm pole in a hole. In 6 m/sec. I got about 30-50W, the higgest output I have seen jet is about 160w in 8-10m/sec. You have to know the power from the wind is a cubic function. Thus the double wind speed has 8 times more power. Combined with a solarpanel and a big 24V battery, it is possible to make a low cost off grid system for a summerhouse. Unfortunatly my windmills battery controller broke down during the 8-10m/s wind. I think this happened, when the battery was fully charged. The controller then shorts the windmills 3 phases and causes the windmill to brake and turning very slow. It is the right way both to prevent overcharging and also protect the windmill from runaway, and exploding in extreme high wind. I am now using a simple 3phase rectifier from windmill to the battery for further test run. Thanks to Banggood for making a low cost entry to alternative energy. In Denmark more than 43% of all el. energy is generated from wind mills.
